Mann/1 A Patented Sept. 15, 1936 UNITED STATES PATENT OFFICE 5 Claims.

This invention relates to gas ranges and particularly to those whichutilize a table top, as a working surface, apart from the burner grids.Heretofore, the cooking burners, which usually are four in number havebeen arranged in the form of a rectangle at one side of the range andhave occupied approximately one-half of the available space on the topof the range. The remaining space has been used as a working surface,but it has been located directly over the oven, where it is too hot tobe of general use while the oven burner is in operation.

One of the objects of my invention therefore, is to provide anarrangement of burners by means of which approximately one-half the topsurface is available as a working surface, and in which half of it islocated above the oven and the remainder above the usual utensilcompartment. In this way, I obtain a hot working surface, and a coldworking surface, whenever the oven is in use.

The arrangement of burners which my invention seeks to accomplish isdiflicult of attainment if the usual compact arrangement of valvehandles is disposed directly in front of its associated burner, thespace requirements would.

necessitate an oven that is too small in height to be practical.Accordingly, I have devised a control arrangement by means of which thegas valves may be compactly arranged at one side of the oven, and bymeans of which the burners may be located in any desired position withrelation to the top of the range. Moreover, I have devised anarrangement wherein the valves are maintained in a cool region at alltimes, and wherein the adjusting mechanism for controlling the mixtureof gas and air is readily accessible for each burner.

' A further consideration in connection with table top ranges is thefact that the'broiler compartment is located directly beneath the ovenand is therefore, too low for convenience.

A further object of my invention therefore, is to maintain the broilerbeneath the oven, which is the most logical position from a standpointof manufacture and utility, and yet, to make it as reasonably convenientfor use, as is the oven.

An additional object is to provide an arrangement which will increasethe efficiency of the burner operation, and yet will conceal all of themechanism except the gas outlet openings.

Referring now to the drawings, Fig. 1 is a front elevation of a stoveembodying my invention; Fig. 2 is a top plan View thereof; Figs. 3, 4and 5 are sections taken on the correspondingly numbered lines in Fig.1; Fig. 6 is a sectional view through a broiler drawer having a modifiedform of pan support, and Fig. '7 is a section taken on an enlarged scalethrough a burner and on the line 1-1 in Fig. 3.

The stove, which I have illustrated has a top In, end walls II, and aback wall 5. The front wall is formed by an oven closure I2, a broilerclosure l3 and a utensil compartment closure I4. The burner arrangementfor cooking purposes is illustrated in Fig. 2 as comprising four burnersl5 which are arranged in longitudinal alignment in the rear portion ofthe range top. The burner openings are preferably oval in shape and areprovided with grids in the usual manner. By arranging the burners in themanner illustrated and described, it is apparent that substantiallyone-half of the top surface is available for a working surface, and thatthere is no necessity to reach across one burner while handling autensil on another, and that there is therefore, no danger of burningthe wearing apparel of the user.

To maintain a compact arrangement of the fuel control handles at oneside of the oven, I provide a manifold 20 which is disposed within therange and in the upper portion of the utensil compartment. The manifoldis connected to a supply pipe 2|, which is shown, as entering the rangefrom the rear thereof.

A valve 22 is connected to the manifold for each of the cooking burners,and each is controlled by rotatable rod 23 which extends to the frontWall and is provided with a knob 24. In the preferred arrangement the.manifold and associated valves are disposed beneath a partition 25, asis shown in Fig. 4, and hence are in a region in which the temperatureis substantially uniform. Thus, there is no danger of the valvessticking on account of their subjection to an excessive degree of heat.

To connect the supply valves with the burners, I provide flexible tubing26, as is shown in Fig. 3, and I extend each tube from one of the valvesto an outlet, which is located adjacent each burner inlet. In Fig. '7,the burner inlet is indicated at 28, at which point the usual aircontrol disc valve is located, and at such point, I provide a needlevalve or orifice, indicated in general at 29. By making the openingsoval in shape, as heretofore described, and by locating the needlevalves at the inlet end of a goose neck tube 30, the needle valves arereadily accessible from the top of the stove for inspection andadjustment. Such mechanism may normally be concealed from view,

however, by a curved plate 3| which is supported on the range topbeneath the periphery of the grids 32, and which extends downwardly andterminates in an opening that is sufficiently large to enclose theburner. The curved plates have a two-fold use, in that they conceal thefuel adjustment members and direct secondary air into the burners,through the openings between the burner arms.

In Figs. 3 and 7 I have shown a plate 9, which extends longitudinally ofthe stove and which provides a supporting medium for a plurality ofburners. The plate has rigidly fastened thereto, as by welding, abracket 8, which is shown as a U-shaped member, one leg of whichsupports the gas conduit 26, and the other leg of which supports a crossplate 1 upon which the burner rests.

To utilize the space over the oven for cooking burners and at the sametime to provide an oven .which has a maximum height, I utilize a falseoven top 33, which extends downwardly from the oven front in an inclineddirection and thence laterally in ahorizontal direction, as is shown inFig. 5. The horizontally extending portion then provides a support forthe two burners, which are located above the oven and enable them to bepositioned at the same level as the remaining burners.

The broiler compartment closure is preferably a drawer, which isslidably positioned within the compartment. The drawer has a pan support35,

that is provided with elevating means to vary its I position verticallywith reference to the drawer. In the preferred arrangement, such meanscomprises a threaded spindle 36 which is attached to the pan, and whichin turn engages a correspondingly threaded socket in a pedestal 31.Thus, the pan support may be elevated or lowered merely by turning it onits axis.

In Fig. 5, the pedestal is illustrated as being mounted directly uponthe bottom of the drawer in which case, it is rigidly fastened thereto.In Fig. 6 however, the pedestal is shown as being fastened to a falsebottom 38 wherefore, it can be removed as a unit from the drawer,whenever desired, as for instance to insert a large roasting pan.

The utensil compartment closure is preferably mounted on concealedhinges, along the line 39, to swing outwardly, and so it is providedwith clearance openings 40 for the valve operating knobs 24. I haveshown only four knobs exposed in view, and so provision must be made forthe oven burner valve and oven heat control mechanism. These arepreferably mounted within'the utensil compartment, just below the valverods 23 where they are readily accessible in the utensil compartment,just below the valve rods 23 where they are readily accessible, wheneverthe utensil compartment door is opened. I prefer to locate the oven andbroiler control mechanism in a concealed location, for they are used soinfrequently, that I deem it advisable to avoid exposed valve operatingmembers as much as possible.

A further feature of my range is the use of a splash plate, which isconnected to the back of the stove and which is provided wit brackets 4|that extend forwardly from it, and t ence downwardly and are attached tothe top I0. In the preferred arrangement, the forward ends of thebrackets terminate adjacent the forward ends of the burners, and thusprovide guards for holding utensils on the range.

The stove legs 42 are preferably U-shaped tubular members that areattached to the bottom of the range and that extend from the front torear as is shown in Fig. 4. These supports provide a sturdy constructionthat can be installed at the factory and shipped with the range, whereasin prior constructions, the practice has been to ship the legs with thestove in dismantled condition.

From the foregoing description, it will be apparent that I have provideda stove, which has many advantages over prior ranges, and which providesa compact structure that may be made principally of pressed steel parts,and therefore produced at low cost,
